Thermal Spray Coatings Equipment and Processes
Powder Flame Spray Equipment allows a wide variety of coatings to be applied
economically. For many coatings and applications it is the best way to achieve
a long-lasting coating, especially on less expensive items which are easily
replaced at low cost on a regular basis (such as a plant outage).
Wire Flame Spray Equipment can be used to apply any coating that can be formed
into a wire including ferrous and non-ferrous metals. Self-fluxing alloys,
ceramics and carbides cannot be sprayed with wire flame spray equipment.
Permeability of coatings produced by this process is generally higher than
the same coating produced by the powder flame spray process. Bond strength
is generally the same as those coatings produced by the powder flame spray
process; although in some coatings it may be up to 33% greater.
Hardness of ferrous metal coatings is generally the same as those coatings
produced by the powder flame spray process; although in some coatings it may
be slightly higher.
HVOF Spray Equipment can be used to apply a wide variety of powder form coatings
(except ceramics).
Most coatings produced by this process (except self-fluxing alloys used in
their fused states) exhibit much higher bond strengths, slightly higher densities,
somewhat higher hardness and much lower permeability than those produced by
powder flame spray equipment.
Coatings are produced using such gasses as hydrogen, propylene and propane
(all combined with oxygen).
Plasma Spray Equipment can be used to apply a wide variety of powder form
coatings (except self-fluxing alloys).
Most coatings produced by this process exhibit higher bond strengths, slightly
higher densities, slightly higher hardness and about the same permeability
as those produced by powder flame spray equipment.
Coatings are usually produced using argon or nitrogen combined with hydrogen
or helium.
Electric Arc Spray Equipment can be used to apply any coating that can be
formed into a wire including ferrous and non-ferrous metals. Self-fluxing alloys,
ceramics and carbides cannot be sprayed with wire flame spray equipment.
Most coatings produced by this process exhibit much higher bond strengths,
about the same densities, slightly higher hardness and much less permeability
than those coatings produced by wire flame spray equipment.
No combustion gasses are used in this process; rather the wire form coatings
are melted by an electric arc and propelled onto the surface being coated by
a stream of air.
